Check back here often for more local event updates from USDA-ARS Pendleton, Oregon. New updates are posted bi-weekly.
- Dan Long is travelling to Akron, CO to test an optical sensor for measuring the seed oil concentration of canola during harvest with a combine. Extreme wetness in the Great Plains has delayed harvest and Dan’s work.
- Representatives with the instrument firm Cosa Xentaur will be at the location in late September to consult with John McCallum on nuclear magnetic spectroscopy to measure the oil concentration in seed and meal samples.
- John Sulik will give the illustrated talk “Basics of spectral imaging for agriculture” at the annual meeting of the Cascade Chapter of Association for Unmanned Vehicle Systems International at Warm Springs, OR on October 1st.

- Stewart Wuest is analyzing data from a field experiment and finding that wheat and grass roots may be the most significant source of long-term soil carbon in a no-till system. Surface residues add to the effect, but are most important for protecting the soil from crusting due to raindrop impact and moderating heat and evaporation.
- Kate Reardon is completing a manuscript with WSU collaborators identifying factors influencing the rates of microbial denitrification in soil with sloping topography.
Informational booth manned by Dan Long and John Williams of ARS, and a local NRCS employee, at the recent community picnic of the Confederated Tribes of the Umatilla Indian Reservation. August 20, 2014.
- John Williams and Dan Long manned a booth to showcase USDA-ARS Pendleton at the annual community picnic of the Confederated Tribes of the Umatilla Indian Reservation. They provided information on agricultural research to K-12 students, parents, and other members of the community. USDA-NRCS personnel also joined ARS to provide additional information under a theme of soil health.
- Dan Long is completing a manuscript describing the use of multiple sensors and collection of on-combine data for post-harvest evaluation of environmental stress in wheat.
Dave Robertson and Aron Boettcher (shown above) are sampling soil water in the oil seed cropping systems research to evaluate water use efficiency. August 26, 2014
- Dan Long and his team are getting materials and equipment ready for planting winter cereals and winter oilseeds into field experiments planned for the 2015 growing season.

Bundle harvest was conducted in long-term no-till and GRACEnet plots on July 29, 2014, and combined harvest was carried out on July 31, 2014. Above is a photo from the bundle harvest in the long-term no-till plots. From left to right are Joe St. Claire, Wayne Polumsky and Aron Boettcher, shown collecting wheat bundles to determine wheat yield, and aboveground biomass production.
Harvest of numerous small plots in all field experiments is now complete. Steve Umbarger uses the Case IH 1470 combine to harvest winter wheat from larger non-experimental areas.
- Dan Long and John McCallum will be leaving for their trip to Malta, Montana to test a new optical sensor on a combine during harvest and obtain grab samples of canola. A mounting plate has been constructed for installing the sensor to the auger housing of a Case New Holland combine. A software interface was written for recording the sensor’s spectra on-the-go and mapping the estimates of seed oil concentration.
Biological Science Technician Aron Boettcher collects post-harvest soil samples from plots that grew different oilseed crops. These samples will be weighed and dried to determine their water content and compute the amount of water consumed by each oilseed over the 2014 growing season.
Kate Reardon collaborated with ARS technician Aron Boettcher to develop an in house method for quantifying glucose and sucrose sugars in nectar from canola flowers. Shown above Aron Boettcher and Hayley Peter-Contesse prepare pollinator exclusion bags.
